This invention relates to chairs and stools made of metal rods or tubes, for example, steel tubes bent in the form of loops and consists essentially in that the base frame consists of a single preferl ably closed loop having two parallel sides and two parallel ends or struts arranged transversely of .the sides, the parallel sides being bent in the shape of a U W or L to form a resilient supporting frame for the seat frame.

The seat frame which if desired may also be sprung. 4 The sides of the base frame may bebent in the form of a U or W open at the front. The

parallel sides include floor enga ing portions and upper horizontal supporting portions connected by intermediate portions. In all instances the upper horizontal portions are yieldingly supported by the intermediate portions. In some instances the upper horizontal portions provide arm rests with relation to the seat frame while the upper transverse ends or struts act to brace the back of the seat frame.

According to the invention also the transverse ends or struts, are bent downwards and below the seat, that is, at the front. they are bent backwards and. at the back forwards. By this means a result is obtained that the transverse ends or struts wlll'not interfere with the comfort of the user of the seat, that is, they are'prevented from coming into contact withthe downwardly de-' pressed elastic seat and with the legs of the user. For example, according to the invention particularly in seats in the form of stools, the side parts of the seat frame may be bentsubstantially in the form of a semi-circle. The-rear end of the upper limb or horizontal portion of the base frame which carries the transverse struts or ends may be curved downwards and forwards. This transverse strengthening then forms at the same time transverse strengthening of the seat frame secured to the base frame.

Other objects as well as the nature, characteristic features and scope of the invention will be more readily apparent from the following description taken in connection with the accompanying drawings and pointed out in the claims.

The invention is clearly illustrated in the accompanying drawings wherein several embodiments of the invention are illustrated, and in which:---

Fig. 1 is a perspective view of the seat frame per se,

Fig. 2 is a perspective view of a chair in which the base frame has the form of a rearwardly open U,

Fig. 3 is a perspective view of a chair in which the base frame is in the form of a forwardly" open U, v

' Fig. 4 is a perspective view of a modified form in which the sides of the base are in the shape of an 8,- 1

Fig. 5 is a perspective view of a modified form of chair in which the sides of the base frame are in the form of a rearwardly open U, the upper horizontal portion serving as arm rests,

Figs. 6, 7 and 8 are perspective views of other modified forms of chairs, and

Fig. 9 is a perspective view of still another modified form of chair wherein an inverted L- shaped base frame is provided in connection with a swivel support.

Similar characters of reference are employed in all of the above described views to indicate corresponding parts.

Referring now, more particularly, to the accompanying drawings especially Fig. 1 there is provided a seat frame constructed of steeltuhing preferably closed and of an oblong shape including side portions a bent downwards at (11' somewhat sem'i-circularly and rearwardly so that the transverse connecting ends b of the frame will be situated below. the seat c and to the rear of the front sitting edge thereof. The side portions aare bent upward so as to constitute a back support d the upper parts being bent away from the face of the netting or covering e of the back support so that the upper transverse end {of the frame will be situated to the rear of the surface of the said back support. This frame which is used in conjunction with the several modifications will hereinafter be referred to as the seat frame.

With reference to Fig. 2 there is provided an improved base frame for, resiliently supporting the seat frame. This base frame is closed and is constructed of tubular stock and, comprises parallel side portions i and transverse ends or struts k. In Fig. 2 the sides are further bent to include lower horizontal or floor engaging portions 1 and upper horizontal seat supporting portions m with intermediate portions 1; between the portions 1 and m so that the portions m are resiliently supported relative to the floor and thereby resiliently support the entire seat frame which is secured in any suitable manner to the upper surfaces of the horizontalportions n. As will be noted the sideportions 'z' in this form are bent to provide a rearwardly open u. In addition the outer terminals of the upper horizontal portions m are bent downwardly as at oand thence forward so that the transverse end or strut It will become situated below the seating surface c, so that the seat is very securely. stiffened at its v front and'rear sides.

Inthe construction shown in Fig. 3 the base frame is provided with a transverse strut hi for increasing the transverse stiffening of the sitting surface. In this form of construction the base frame is arranged as a forwardly open U-shaped frame, the upper portions m serving .to yieldingly support the seat frame.

In the form of construction shown in Fig. i,

the base frame has its parallel side portions bent in an s-shaped formation, the intermediate portions in this instance having the seat frame secured thereto as at p while the upper horizontal portions q form arm rests and the upper transverse end or strut 7 forms a brace for the back d of the seat frame.

In the modification shown in Fig. 5 the base frame has the form of a rearwardly open U the form being substantiali; as that shown in Fig. 2 with the exception that the seat frame is secured as at s to the intermediate portions while the upper transverse end or strut t serves as a brace for the back d of the seat frame.

In the arrangement shown in Fig. 6 the seat is pivotally suspended at the forward end of the horizontal portions of the base frame as at it. At its rear the seat frame may be secured in position by means of pegs to be introduced into the openings U in the upright portions of the base frame so that the position and inclination of the seat may be varied. With this construction an additional strut he becomes necessary for the back and seat of the chair, provided special stiffening means for the seat are required at the vicinity of its rear edge or rear portion.

In the modified construction shown in Fig. 7 the sitting frame a is supported in a substantially S-shaped base frame the forward end of the seat frame being secured as at 10 near the upper horizontal portion 0: these portions cooperating with main loop i1 and the transverse lower end ii are situated at the rear portion of. a piece of furniture in order not to interfere with the comfort of the user.

In the form shown in Fig. 9 the base frame has its sides i in the form of an inverted L while only the upper horizontal portions is are provided to receive the seat. Insteadof employing the lower horizontal portion the side portions are connected to a collar 1: swivelled to the supporting foot z. The horizontal portions is form a resilient support as is apparent for the seat frame a.' V

In connection with the several figures shown attention is directed to the fact that the base frame has its side portions bentaupon themselves so as to form only two substantially upright resilient supports and upper and lower horizontal limbs, the upper limbs forming cantilevers. In other words each embodiment has a horizontal portion which supports the seat frame yieldingly with respect to the floor surface.

It is also to be noted in connection with the seat frame that in all forms disclosed in addition to effecting an arrangement whereby the yieldable seating surface 0 acts to support the user that the front cross piece b serves as 9. connecting brace for the side portions of the base frame.

It is believed in view of the foregoing that a further detailed description of the operation of the invention is entirely unnecessary. Likewise it is believed that the advantages of the invention will be readily apparent.
